voracity \vo-RAEH-seh-ti\ (noun) - An enormous appetite, uncontrollable hunger, ravenousness.
"Madeleine has an insatiable voracity for German classical music."
From Latin vorax "ravenous" from vorare "to swallow, devour." The same word emerges in French as "voracite," in Italian as "voracita," and in Spanish as "voracidad." Today's word is akin to vorago "chasm, abyss" and its adjective voraginous "gaping, resembling a chasm or abyss," things that can greedily swallow you up.
